Article
Power to gas energy storage is usually conceived as a carbon utilization technology, as it consumes CO2 for the production of synthetic fuels. However, some authors put in doubt its potential for mitigating global warming, since CO2 is released to the atmosphere when the synthetic fuel is used. In this paper, we demonstrate that power to gas can be...

Some remarkable hybridizations to enhance Power to Gas are those that avoid carbon capture penalties. A suitable option to this end is the hybridization of PtG with an oxy-fuel combustion process. In oxy-fuel combustion, pure oxygen is used as comburent instead of air. Conventionally, requiring an air separation unit to produce the oxygen leads to...

Project
This project seeks to develop sustainable power-to-gas‒based strategies driven by low-carbon electricity towards the decarbonization of energy-intensive metal manufacturing, focusing on iron & steel processes. These strategies are to enable switching from fossil feedstock/fuels to electrolytic hydrogen and derivatives to supply process heat, reducing agents and electricity, while minimizing changes in process equipment and cost. The integrated power-to-gas‒metal manufacturing processes are benchmarked with alternative decarbonization approaches. This project is led by Khalifa University, United Arab Emirates, in collaboration with the University of Zaragoza, Spain.

This Special Issue comprises selected papers on the decarbonization of industry by using green hydrogen and power to X processes. From a carbon neutral and economic perspective, green hydrogen and synthetic fuels should be targeted at industries that are inaccessible to direct electrification (e.g., cement, glass, paper mills). A suitable approach is to use these fuels in niche markets that cannot decarbonize their processes by renewable electricity, either because CO2 is naturally produced from the chemical reactions during raw material processing or because the required operating temperatures are much easier to achieve through combustion than through electrification. In that sense, this Special Issue aims to cover a variety of analyses of the integration of green hydrogen and synthetic fuels in different industries as competitive alternatives against renewable electrification. Papers selected for this Special Issue will be subject to a rigorous peer review procedure with the aim of a rapid and wide dissemination of research results, developments and applications. This journal has 2.576 impact factor, and ranked as Q2 in Environmental sciences in 2019 according to Journal Citation Reports. Deadline is 30 September 2021.
